| Abstract: | According to speed sensorless vector control of asynchronous motor based on cascaded high voltage converter, a model reference adaptive system(MRAS) implemented in two axis rotating reference frame is studied to identify the rotor speed of an asynchronous motor.Simulation and experimental results show that the method of speed identification is easy to realize,and can estimate the flux and speed with good accuracy. |
